Provided is an intraocular lens having less surface adhesion. An intraocular lens 1 comprises a copolymer that includes, as constituents, an acrylate-based monomer component A and a methacrylate-based monomer component B. The intraocular lens 1 includes a surface section 12 that includes the surface of the copolymer, and a center section 14 which is more toward the center side than the surface section 12. The surface section 12 comprises a methacrylate-rich layer containing more of component B as the monomer component than does the center section 14. L'invention concerne une lentille intraoculaire présentant moins d'adhérence de surface. Une lentille intraoculaire 1 comprend un copolymère qui comprend, en tant que constituants, un composant monomère A à base d'acrylate et un composant monomère B à base de méthacrylate. La lentille intraoculaire 1 comprend une section de surface 12 qui comprend la surface du copolymère, et une section centrale 14 qui est plus proche du côté central que la section de surface 12. La section de surface 12 comprend une couche riche en méthacrylate contenant plus de composant B en tant que composant monomère que ne la section centrale 14. 表面の粘着性が低減された眼内レンズを提供する。本発明により提供される眼内レンズ１は、アクリレート系モノマー成分Ａと、メタクリレート系モノマー成分Ｂと、を構成成分として含む共重合体からなる。また眼内レンズ１は、共重合体の表面を含む表面部１２と、表面部１２よりも中心側の中心部１４と、を含む。そして表面部１２は、中心部１４よりも、モノマー成分としてモノマー成分Ｂを多く含むメタクリレートリッチ層を構成している。
